Absolutely thrilled with my recent purchase from Lusterblue! I recently purchased a stunning natural teal sapphire and had it custom designed into an engagement ring. The craftsmanship is impeccable, and their customer service was incredibly throughout the process. I couldn't be happier with the final result. Highly recommend!

I’ve made two purchases from Lusture Blue and both have been great. A pair of sapphire earrings and two sapphire gems for a ring. Asshab has been really helpful throughout the process.

Luster Blue is your go-to for top-quality, ethically sourced natural sapphires. Unlike others, our sapphires are 100% natural - no synthetic methods, extreme heat treatments, diffusion, irradiation, glass filling, or oiling are used. This means our sapphires maintain their true beauty, rarity, and are more valuable than treated ones. Our collection includes a wide range of colors: vibrant blues, pinks, yellows, pure whites, and other unique shades. Each sapphire is precisely cut by us and can be bought as is (loose) or set in personalized jewellery just for you. Our team of jewellery and gemstone experts will guide you in creating your dream sapphire piece. Explore our extensive selection of natural sapphires and bespoke sapphire jewellery to see why Luster Blue stands out in the world of gemstones.
